In a previous post, I built a pair of space buckets to start my 3000K and 5000K peppers in. The buckets worked excellently – they made it really easy to control temperature, humidity and airflow, and they got my peppers off to a great start. One of the best features of the buckets was how much light made it from the COB down to the plant canopy – especially after the walls were painted white. Off of a single Vero 18 COB, at the very bottom of the bucket I was getting a PPFD of 500 µMol/m2/S and at 12″ away from the COB, I was getting 1,100 µMol/m2/S. Having seen how well these worked, earlier this week, I set out to test out another popular “Space” device: the mighty Space Tote. Continue reading
There’s a ton of information out there about finding drivers for your 4+ COB systems, but not a whole lot regarding drivers for setups with only 1 COB. The main problem is that most of the popular drivers for bigger systems have constant current ranges that are too high for a single COB, so they won’t work. We’ll need to find smaller drivers with similar characteristics in order to properly power your single COB grow light.
This post will examine a few different constant current drivers that will work for single COBs of different voltages. Note that these models are chosen with 120V AC power in mind, and may not work if your mains are 230V or whatever else. Always check the input voltage rating in the data sheet to be sure.
